If you act fast, you’ll never need to worry about storage constraints on your mobile device again (as long as it accepts microSD). Turn any phone into a storage beast by taking advantage of today’s Gold Box deal from Amazon. Up for grabs are a slew of SanDisk storage options, but most notably for mobile users are the 32GB and 64GB microSD cards.

For today only (and while supplies last), you can get a 32GB SanDisk Ultra microSD card for an insane $23.99 or 64GB for $49.99. A perfect match to your new Samsung Galaxy S III, if you don’t mind me saying so. $50 is a small price to pay for storage peace of mind, so say goodbye to the days of trying to decide on which apps you need to uninstall in order to make room for others.

And this, my friends, is why all mobile devices should have microSD slots.
